A 28-year-old Whitefish Bay man who supplied a lethal dose of heroin to a woman who overdosed in 2006 has been sentenced to seven years in prison.

Timothy J. Manikowski was also sentenced Tuesday to an additional five years in prison on two unrelated counts of being party to the crime of manufacturing and delivering heroin, according to court records.

Brenda M. Schneeberg, 24, was found dead in her Wauwatosa apartment Nov. 4, 2006. She had overdosed on a mixture of heroin and Fentanyl, an opiate derivative 80 times more powerful than morphine.
